THOMAS J. CAI-TILL, OF CORPUS CHRISTI, TEXAs.

FLUSH-VALVE.

Specification of Letters Patent.

Patented Nov. 7, 1916..

Application filed May 13, 1916. Serial No. 97,347.

To all whom it may concern Be it known that I, THOMAS J. CAI-IILL, a citizen of the United States, residing at Corpus Christi, in the county of Neuces and State of Texas, have invented a new and useful Flush-Valve, of which the following is a specification.

The device forming the subject matter of this application is a valve for a flush tank, the valve being of that general type in which mercury is employed to effect a seal. Attention is directed to my co-pending application, Serial No. 56,543, for Letters Patent on a clutch valve, filed October 18, 1915, allowed November 26, 1915.

The invention aims to provide novel means whereby the cup or trough which contains the mercury is held'in place, and to provide novel means for holding in .place the element which dips into the mercury within the cup or trough to effect the seal.

The invention aims to provide novel means for guiding and directing the movement of an outer tube, which supports a float and an element adapted to dip into the mercury trough.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with in the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings: Figure 1 shows in vertical longitudinal section, a flush valve constructed in accordance with the present invention; and Fig. 2 is a cross section on the line 2-2 of Fig. 1.

In the accompanying drawings the numeral 1 indicates a portion of the bottom of a flush tank, through which passes a sleeve 2. Formed integrally with or otherwise secured to the sleeve 2 is an outer trough or shoulder 3. Threaded at 4 onto the sleeve 2 is a nut 5. The nut 5 and the outer trough or shoulder 3 lie on opposite sides of the bottom 1 of the flush tank. Packing washers 6 may be interposed, on the one hand, between the trough 3 and the upper face of the flush tank bottom 1, and, on the other hand, between the lower face of the flush tank bottom 1 and the nut 5. Obviously,

when the nut 5 is turned, the sleeve 2 will be securely assembled with the bottom 1 of the flush tank, and a leakage about the sleeve 2 will be prevented. Detachably seated within the outer trough 3 is an iIiner trough 7 which is made out of some inamalgamative material, such as hard vulcanized rubber. Assembled with the upper end of the sleeve 2 is a spider 8, held to the upper end of the sleeve 2 by threading 9 or otherwise. Mounted on and secured to the spider 8 is an inner tube or guide 10. A refilling pipe 11 extends from the ball cock (not shown), and opens into the upper end of the inner tube 10.

Mounted to reciprocate vertically on the inner tube or guide 10 is outer tube 12, carrying at its upper end a spider 14 and equipped at its lower end with a spider 15,

these spiders cotiperating with the inner tube 10 to direct the vertical sliding movement of the outer tube 12. Secured to the lower end of the outer tube 12 is an inner cup 16 which preferably is made of inamalgamative material, such as hard rubber. The inner cup 16 includes an extension 24 adapted to dip into the mercury in the inner trough 7. The inner cup 16 is provided with a continuous circumscribing shoulder 17 which rests on the upper edges of the troughs 3 and 7 or one of them. Assembled with the outer tube 12 and held thereon by nuts 19 or otherwise, is an outer cup or float 18 which is of larger diameter than the trough 3. Assembled with the outer tube 12 is a bracket 20 embodying a cross pin 21 receiving a loop 23 formed at the lower end of the lifting member 22.

In practical operation, the extension 2 1 of the inner cup 16 dips into the mercury in the trough 7, the circumscribing shoulder 17 cooperating with the upper edges of the troughs 3 and 7 to form an additional seal. This additional seal afforded by the parts above enumerated is of peculiar utility if the mercury in the trough 7 is depleted from any cause. The outer tube 12 together with the float 18 and the cup 16 may be raised by means of the lifting member 22, whereupon water within the flush tank 1 will flow through the spider 8 and downwardly through the sleeve 2, the parts being buoyed up by the outer cup or float 18 until the Water falls suliiciently to permit the shoulder 1'? to seat on the upper edges of the troughs 3 and 7 Having thus described the invention What is claimed is 1. In a device of the class described, a flush tank including a bottom; a sleeve assembled with the bottom; a trough carried by the sleeve; a spider assembled With the sleeve; a guiding means carried by the spider; inner and outer connected caps slidable on the guiding means, the inner cap embodying an extension adapted to dip into the trough, the outer cap being of greater diameter than the trough; and means for lifting both caps.

2. In a device of the class described, a sleeve; a circumscribing trough carried by the sleeve; a second trough in the first specified trough and fashioned from inamalgamative material; a cup adapted to dip into the inamalgamative trough; a float; and means for connecting the float With the cup.

3.-In a device of the class described, a flush tank bottom; a sleeve therein; a trough carried by the sleeve; clamping means on the sleeve, the clamping means and the trough cooperating With opposite faces of the bottom to hold the sleeve on the bottom; a cup adapted to dip into the trough; a float; and means for connecting the float with the cup.

fl. In a? device of the class described, a

Copies of this patent may be obtained for five cents sleeve a trough assembled with the sleeve; a cup dipping into the trough and provided With a circumscribing shoulder adapted to rest on the top of the trough; means for raising and lowering the cup; and afloat operatively connected with the cup,

5. In a device of the class described a flush tank bottom; a sleeve extended through the'bottom; an outer trough carried by the sleeve and coa-cting with the inner face of the bottom to support the sleeve; an inner trough Within the outer trough and fashioned from inamalgamative material; a cup fashioned from inamalgamative 'material and dipping into the inner trough, the cup being provided With an outstanding circumscribing shoulder resting on the upper edge of one trough; an outer tube connected with the cup; an inner'tube located Within'the' outer tube and constituting a guide for the outer tube; a splder connecting the inner tube with the sleeve; and a bell-shaped float carried by the outer tube and surrounding the outer trough. I

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa-r ture in the presence of tWo- Witnesses.
